Subject: [PATCH 0/3] arm64: dts: PCI: lx2160 use fsl,lx2160ar2-pcie

Only lx2160 rev1 use mobivel PCIe controller. Rev2 switch to use designware
PCIe controller. Rev2 is mass production version. Rev1 will not be
maintained and used in future. And no road map to use mobivel PCIe
controller.

Driver part:

Bjorn and mani have some concern about delete it directly.

V2 try not to build defaultly to make change visuable to do prepare for
futher clean up.

Dts part.
previous version:
https://lore.kernel.org/imx/ac41ac85-fdf5-4aa8-953d-6b3ab3c23f37@kernel.org/

2020 yang li try to do the same thing.
https://lore.kernel.org/all/20220817202538.21493-2-leoyang.li@nxp.com/

Olof Johansson report (HoneyComb LX2K) use ver1 chip. NXP can't prevent
3rd parting to build their production with evaluation chip. Rev1's
informaiton have been removed from nxp.com.

Any way, to reduce impact, just apply rev2 to nxp's boards, qds and rdb.
It can apply to more boards gradually.
